The AC30h just arrived.

Some tubes were pulled for transit. But not labeled. I can’t find a diagram anywhere. Doesn’t seem to complex, but I’d like to get it right without smoking anything.

On the bottom of the head is where these apparently go.
I have two ECC83 and four EL84s. That’s an ECC83 to the left. Not sure why it wasn’t pulled.

Do they just go in order. Two more ECC83s, then four EL84s?

Any help is appreciated
 
Every Chinese VOX AC30 I have worked on looking at the back of the amp the EL84 tubes are on the right hand side
the 12AX7 are on the left

 
Just found something that looks like mine. I’ll install the EL84s right io left then the ECC83s.

Looking at the photo facing the front bottom of the amplifier:
looks like the first four tubes on the right are EL86 and the 3 tubes on the left are 12AX7.

The 3 preamp tubes are closest to the input jacks.
The 4 output tubes are closest to the Vox name plate and power switches.
